Ingredients for Easy Shredded Zucchini Casserole

This recipe keeps it classic, with everyday staples and just the right amount of seasoning.

Core Ingredients

• Zucchini (4 cups shredded) – About 2 medium zucchinis. The star of the show. It gets tender and delicious after baking, especially when the moisture is removed properly.

• Small onion, finely chopped – Adds depth and a savory touch.

• Garlic (2 cloves, minced) – A little goes a long way here, and it brightens everything up.

• Large eggs (2) – These help bind everything together.

• Shredded cheddar cheese (1 cup) – Brings that melty, gooey texture and a bold flavor.

• Grated Parmesan cheese (½ cup) – Adds a salty, nutty layer that complements the cheddar.

• Breadcrumbs (½ cup, optional) – For those who love a crispy topping. Totally optional, but highly recommended.

• Salt (1 tsp) – Draws out moisture from the zucchini and enhances flavor.

• Black pepper (½ tsp) – A simple seasoning that brings it all together.

• Paprika (½ tsp, optional) – Adds subtle warmth and color.

• Olive oil or melted butter (2 tbsp) – For greasing the dish and drizzling over the top to get that golden finish.

• Fresh parsley or chives (for garnish) – Optional, but great for a pop of color and freshness.

Substitutions and Tips

• No cheddar? Try mozzarella for a milder, gooier bite or Gruyère for something a bit fancier.

• Egg-free option: Use a flaxseed egg or commercial egg replacer. Just note the texture may be slightly different.

• No breadcrumbs? Crushed crackers or almond flour can step in for a similar crunch.

• Want it dairy-free? Use dairy-free cheese alternatives and skip the Parmesan. Nutritional yeast can add a cheesy flavor without the dairy.

• Spice it up: Add a pinch of red pepper flakes or some chopped jalapeños if you like heat.

Best Zucchini for This Casserole

Let’s talk zucchini. Not all squash is created equal, especially when it comes to casseroles.

• Medium zucchini (about 6–7 inches long) work best. They’re not too watery, and the seeds are still small.

• Avoid overly large zucchini from the garden unless you scoop out the seeds—they can be too mushy and bland.

• Always shred it fresh. A box grater works fine, but a food processor makes the job even easier.

• Don’t skip the draining step. Zucchini holds a lot of water. Salting it and squeezing out the excess moisture makes the difference between creamy casserole and soggy mess.

Tip: If you’re in a rush, place the shredded zucchini in a clean dish towel, twist tightly, and wring out as much water as possible. It’s a game-changer.

Kitchen Tools You’ll Need

You don’t need a fancy kitchen to pull this off. Just a few basics, and you’re good to go.

Must-Have Tools

• Box grater or food processor – For shredding zucchini quickly.

• Large mixing bowl – Everything gets mixed in one place.

• 9×9-inch baking dish – This size gives you the perfect thickness and a nice golden crust.

• Clean kitchen towel or cheesecloth – To squeeze the water from the zucchini.

• Oven – Standard 375°F does the trick.

Nice-to-Have Tools

• Mandoline slicer – Great for speed and even texture if you’re working with lots of zucchini.

• Microplane – Ideal for finely grating the Parmesan.

• Silicone spatula – Helps scrape every last bit into the baking dish.

How to Make Easy Shredded Zucchini Casserole

Alright, time to roll up your sleeves and turn that bowl of shredded zucchini into something warm, cheesy, and absolutely irresistible. This step-by-step guide walks you through the entire process with simple, no-stress instructions. If you can mix, you can make this.

Let’s get started.

Step 1: Prep the Zucchini

This step is key. Zucchini is full of water, and if you skip this part, you’ll end up with a watery casserole instead of a creamy, cheesy bake.

• Start by shredding about 2 medium zucchinis to get 4 cups. A box grater works great here.

• Place the shredded zucchini in a colander set over the sink or a bowl.

• Sprinkle with 1 teaspoon of salt and toss gently. Let it sit for at least 10 minutes.

• Then take a clean kitchen towel, wrap the zucchini inside, and squeeze as much moisture out as you can. You’ll be surprised how much water comes out—don’t skip this step.

Tip: The drier your zucchini, the firmer and tastier your casserole will be.

Step 2: Mix the Filling

This is where all the magic comes together.

In a large mixing bowl, combine:

• The drained zucchini

• 1 small finely chopped onion

• 2 cloves of minced garlic

• 2 large eggs

• 1 cup shredded cheddar cheese

• ½ cup grated Parmesan

• ½ teaspoon black pepper

• ½ teaspoon paprika (optional)

Give everything a good stir until it’s evenly mixed and coated. You want the eggs and cheeses to hold everything together, so don’t be afraid to really get in there and stir.

Optional: You can sneak in extras here—like chopped cooked bacon, sautéed mushrooms, or a handful of cooked rice or quinoa to bulk it up.

Step 3: Assemble the Casserole

Grease a 9×9-inch baking dish with a little olive oil or melted butter to prevent sticking and help create those golden edges.

Pour the zucchini mixture into the dish and spread it out evenly with a spatula.

For a crispy topping (highly recommended):

• Mix ½ cup of breadcrumbs with 1 tablespoon of melted butter or olive oil.

• Sprinkle over the top of the casserole.

If you’re skipping the breadcrumbs, you can still drizzle a bit of olive oil over the top for that golden finish.

Step 4: Bake

Place the dish in a preheated 375°F (190°C) oven.

Bake for 25 to 30 minutes, or until:

• The center is set (not jiggly)

• The top is golden and slightly crisp

You’ll start to smell the cheese and garlic filling your kitchen with cozy, savory aromas—it’s hard to resist.

Optional finishing touch: For an extra crispy top, you can switch the oven to broil for the last 2 minutes. Just keep a close eye on it so it doesn’t burn.

Step 5: Serve

Let the casserole cool for about 5 to 10 minutes before slicing. This gives it time to firm up, making it easier to serve.

Top with chopped parsley or fresh chives for a little color and freshness.

It’s best served warm, either on its own or alongside grilled chicken, roasted vegetables, or a crisp green salad.

Tips for Success

Want a flawless casserole every time? Here are some insider tips to help you nail it.

• Really squeeze that zucchini. This is the #1 key to avoiding a watery bake.

• Use sharp cheddar. It adds more flavor than mild cheddar and balances the zucchini nicely.

• Add flavor boosters. Crumbled bacon, sun-dried tomatoes, or fresh herbs can totally customize the flavor.

• Don’t overbake. Once the top is golden and the center is set, it’s ready. Overbaking can dry it out.

• Let it rest. Giving the casserole a few minutes to settle before serving helps the texture hold together beautifully.

How to Store Easy Shredded Zucchini Casserole

Whether you’re meal-prepping for the week or just saving leftovers, this casserole stores like a dream.

At Room Temperature

It’s best to serve this dish warm or at room temp. That said, it shouldn’t sit out for more than 2 hours. After that, transfer it to the fridge.

In the Refrigerator

• Let the casserole cool completely before storing.

• Store leftovers in an airtight container or cover the baking dish tightly.

• It will keep in the fridge for 3 to 4 days.

To reheat: Simply warm individual portions in the microwave or reheat in the oven at 350°F until hot.

Freezing Tips

Frequently Asked Questions (FAQs)

Can I make this ahead of time?

Absolutely. You can assemble the casserole, cover it, and refrigerate it up to 24 hours in advance. Just pop it in the oven when you’re ready to bake.

How do I make it gluten-free?

Easy fix—just skip the breadcrumbs or use gluten-free ones. The rest of the recipe is naturally gluten-free.

Yes, but it must be thawed and drained very well. Frozen zucchini holds a lot of water, so be extra thorough when squeezing out moisture.
